Joan Rhodes (1921-2010) first appeared in variety shows at the Nottingham Empire in the 1950s. She had answered an advertisement for 'freaks' in the Stage newspaper. Joan was petite and blonde with the good looks of a chorus girl: the only thing 'freakish' about her was her strength. She could bend steel bars with her teeth, break six inch (15 cm) nails and tear telephone directories in half.

Joan Rhodes said that she had discovered her strength at the age of 12 while working in her aunt's public house, where she surprised the customers by lifting the heavy beer barrels. At 14 she was working in a circus as a strong man's assistant and, convinced that she could perform the same tricks, began to rip up telephone books. She tried working as a model and a dancer, appearing with the internationally known dance troupe, the Bluebell Girls, in the South of France, but carried on performing feats of strength for her own amusement and then decided to try and make a career from her unusual skills. Her employer at Nottingham wanted her to wear a leopard skin, the traditional costume of the circus Strongman, but Joan Rhodes wanted to maintain her feminine appearance. She became 'the Mighty Mannequin', showing off her 50-centimetre waist in evening dresses and diamanté-covered leotards. Her green leotard, with matching skirt and cape, was worn with fishnet tights, gold high-heeled shoes and a small tiara. The skirt and cape could be removed when she began her act. She would also wear feather boas and feathered headdresses to add to the glamour.

Joan Rhodes appeared on television and in cabaret in theatres and nightclubs around the world. In interviews she said that she preferred working in cabaret because 'the audience are so close. They can see if any of my equipment is faked'. She calculated that during her 25-year career she had torn up 25,000 telephone books and bent more than two and a half tonnes of nails.
